Dementia and the sense of smell

Dementia and the sense of smell

Could there be a link between dementia and losing your sense of smell? New, cutting edge research indicates there is a possibility. Moreover, the aim is to identify the beginnings of Alzheimer’s or dementia in people. The elderly are living longer nowadays. This is due to better nutrition, improved living conditions and better healthcare. However, there is a flip side to this good news. That flip side is the diseases, such as dementia, associated with old-age.

Here, at Gold Age Australia, Camberwell Gardens, taking care of the elderly is our daily task. As a result, we have acquired a great deal of experience. Moreover, we know how difficult it is to care for an elderly loved one at home. Therefore, we hope the following information we have gleaned for you will be helpful.

The research

Research bodies worldwide are interested in tackling these problems. Everyone agrees the elderly should enjoy a premium quality-of-life. There is no point in living longer if you are in poor health or suffering. Furthermore, ignoring bad health is not going to make it go away.

One university, McGill in Canada, has done a study on loss of smell. They found connections between Alzheimer’s, loss of smell and other biological indicators. Upon completing the study, McGill University published their findings in The Official Journal of the American Academy of Neurology.

The objective

McGill stated their objective as the assessment of odour identification as an indicator of Alzheimer’s disease. Particularly as a pre-symptomatic marker. The patients were normal ageing individuals. Particularly, those indicating an increased risk of Alzheimer’s or dementia.

The methodology

They began by assessing 274 members of a section of healthy ageing persons. However, they had family members with a history of AD dementia. They were looking for a cross-sectional association of odour identification. Their analyses involved considering age, cognition, APOEε4 status, education and sex as covariates. Furthermore, they used the University of Pennsylvania smell identification tests amongst others. These measure odour identification as well as cognitive performance.

The results

The conclusions were that reduced odour identification is sometimes associated with lower cognitive score and older age. Therefore, it may be a practical and inexpensive biomarker of AD pathology.

In conclusion

Dementia care is a very costly health problem in Australia. Early identification could result in savings of $26.8 billion over the next 20 years. Furthermore, the savings could be in the order of $120.4 billion by 2056.

If you or a loved one is affected by dementia, please call the National dementia helpline on 1800 100 500. Additionally, they offer advice and support 24 hours a day.
